This compact sized (A5) user manual (Sony Xperia XA1) proved to be an asset for quickly referencing information without the usual hassle of scrolling through on-screen pdf type formats: It is always nice just to have the pages open (the upgraded ringbound version option selected) to view. The page binding with protective plastic front & back sheets is also a good idea The script copy is in greyscale/monochrome, which the text was mostly readable without too much trouble. However, in my view, a colour version option would be of benefit for this type of mixed text, icon & screenshot graphics' content: Maybe the colour (e.g., HiRes laser) printing of this manual would be an expense too far though(?) Although this manual supplied, in this instance for a client's use, I did proof-read through the contents of this manual and found it very useful, especially for product initial setup information. It has also the great ability to add small sticky-back ‘post-it' notes to quickly identify pages: Something that doesn't quite work for the 'on-screen' format the same easy way! In summary: Pros: Compact handy sized (A5), read anywhere access, flat down read ring binding, easy to 'tag' using 'post-it' notes for client instructional use etc.. Cons: Greyscale (monochrome) readability marginally ('grainy') with graphics & screenshot items, greyscale contrast variable across pages OTC Ltd delivered this manual very promptly and in good order: Excellent service and recommended to all.
